The Secrets of the Oracle is one of my favorite oracle books. Instead of a few curses, they provide new curses, feats, mysteries and archetypes that leap over other 3rd party supplements in terms of innovation for the Oracle. The Rot mystery is my favorite. A flavorful undead take on the class that gives the Shaman feeling I was hoping to get elsewhere. There is also an archetype that allows a player to indulge in hallucination drugs and receive medicinal benefits.

Iron Uses: If you play an oracle or know anyone who is about to play an oracle, this is a the supplement you want to pick through before making your decision.
